I would assume it's hit around 1.5m w/w, or slightly more, and atleast shipped the 2m copies, or near it. However, I don't understand why KZ2 is getting hyped so much, as the first one recieved under 80% reviews from Gamerankings.com Its not like its Fallout , or Forza which were hyped due to cult status (or poor sales atleast)

 That's why I was trying to see the sales number, we all have pretty much agreed that it sold more than 1 million world wide, wouldn't it be in the charts then?
